3. Grapes
Like berries, grapes contain fiber and antioxidants. Specifically, grapes contain an antioxidant called resveratrol, which may help prevent further liver damage in people with NAFLD. Studies show that people with NAFLD who take resveratrol supplements made from grape extract may have less inflammation.

7. Coffee
Coffee is good for liver health, but it works best when you don’t add a ton of sugar because excess sugar is bad for your liver. Coffee has anti-inflammatory and antioxidant properties, and both decaf and caffeinated coffee seem to be beneficial. Studies show that diterpenes in coffee may help with detoxifying actions, which can be beneficial for people with liver fibrosis and cirrhosis.

Tea, specifically green tea, contains bioactive compounds that have antioxidant and anti-inflammatory effects. Studies show that these compounds, including catechins, can also help lower the risk of NAFLD. Green tea catechins may also help prevent liver cancer.
